# Build a compiler for a given target, using one or more existing simple
# cross compilers.

# This can be used to build a native compiler for an aribitrary target, or to
# build a more portable and capable cross compiler for an arbitrary host.

# The new compiler is built --with-shared and has uClibc++ installed, and is
# statically linked against uClibc (for portability) unless BUILD_STATIC=none.

# Building a cross compiler requires _two_ existing simple compilers: one for
# the host (to build the executables), and one for the target (to build
# the libraries).  For native compilers both checks test for the same thing.
